Example Calculation for a single phase 5HP air compressor:

Let’s illustrate the generator sizing process with an example using a 5HP air compressor operating at 230V.

Assumptions:

• Starting current: 30 amps
• Running current: 20 amps

Step 1: Find Starting Power: Starting Current = 30 amps

Step 2: Calculate Surge Watts: Surge Watts = Starting Current × Voltage Surge Watts = 30 amps × 230V = 6900 watts

Step 3: Compute Running Watts: Running Current = 20 amps Running Watts = Running Current × Voltage Running Watts = 20 amps × 230V = 4600 watts

Step 4: Sum Surge and Running Watts: Total Power Requirement = Surge Watts + Running Watts Total Power Requirement = 6900 watts + 4600 watts = 11500 watts

Step 5: Select Generator Size: Opt for a generator with a capacity slightly higher than the total power requirement. For this case, a generator with a capacity in the range of 12000-13000 watts would be a suitable choice.

By diligently following these calculations, you can confidently determine the correct generator size (around 12000-13000 watts) to effectively operate your 5HP air compressor at 230V. Remember, selecting a generator with a slightly greater capacity helps manage the initial starting current and any additional power demands that may arise.
